ASHBURN, Va. - The Washington Redskins will have Robert Griffin III back in the lineup Sunday when they take on the Philadelphia Eagles barring any setbacks to the sprained lateral collateral ligament in his right knee, head coach Mike Shanahan said Thursday.

Shanahan said Griffin is not fully healed but is on the right track.

"It's going to be day by day. If there's no setbacks, doctors feel he should be ready to go," Shanahan said following Griffin's second full practice this week. "He had a good practice. Obviously he's not 100% yet. Everybody knows that."

Griffin practiced fully Thursday alongside fellow rookie quarterback Kirk Cousins, whom the Redskins can thank for helping pull out an overtime win two weeks ago vs. the Baltimore Ravens - after Griffin was injured in the fourth quarter - before orchestrating a 38-21 victory vs. the Cleveland Browns last Sunday. Those wins, paired with three others after the team's Nov. 11 bye have put Washington (8-6) in control of their playoff fate. Wins vs. the Eagles this weekend and the Dallas Cowboys in the regular-season finale would ensure a playoff spot.

"It's awesome," Griffin said Wednesday. "We came back from the bye with one mission, and that's the mission that we're still on. We control our own destiny, and we did what we were supposed to do - we won. That's what we have to continue to do. Guys can't get happy now. We still have one game and then another game after that."

Cousins is 28 for 39 passing over the last two games with 355 yards, three touchdowns and an interception. Griffin's 2,902 passing yards and a 18 touchdowns come with 748 yards on the ground. Fans would like to see him toss the ball away instead of taking off downfield - which got his knee bent backwards by Ravens all-pro Haloti Ngata - but Griffin says he doesn't plan on tailoring his game in light of the injury.

"I think the day I think about throwing the ball away at the beginning of a play, I should stop playing," he says. "It's just something that happens. I've thrown the ball away this year, but it's not something you take into a game plan. 'Alright. I'm going to go 1-2 and throw it out of bounds.' I just think that's a faulty approach to the game, but I get where everyone is coming from. I continue to protect myself. This latest injury could have happened to anybody. I was getting down. It is what it is, and I have to move on from that."

Wide receiver Pierre Garcon - Griffin's No. 1 target when healthy - also practiced fully Thursday despite his torn foot ligament. Right tackle Tyler Polumbus sat out Thursday with a concussion suffered Sunday, and his status is up in the air.
